Plants, scientists say, transmit information about light intensity and quality from leaf to leaf in a very similar way to our own nervous systems.

“Every day or week of the season has… a characteristic light quality,” said Professor Stanislaw Karpinski from the Warsaw University of Life Sciences in Poland, who led this research.
“So the plants perform a sort of biological light computation, using information contained in the light to immunise themselves against diseases that are prevalent during that season.”

Professor Christine Foyer, a plant scientist from the University of Leeds, said the study “took our thinking one step forward”.
“Plants have to survive stresses, such as drought or cold, and live through it and keep growing,” she told BBC News.
“This requires an appraisal of the situation and an appropriate response – that’s a form of intelligence.”
